Description
Technical Field
The invention relates to the technical field of polyester fabric dyeing methods, in particular to a dyeing method of a polyester fabric for high-color-fastness luggage fabric.
Background
The terylene has excellent setting performance, and flat, fluffy or pleated forms and the like generated after the terylene yarn or the fabric is set can be enduringly unchanged after being washed for many times in use. Terylene is also known as Terylene, and Americans are also known as Dacron. When it appears on the hong Kong market in China, it is well known that people translate it into "sure" according to the word Cantonese. The terylene is the simplest of three synthetic fibers and has lower price. In addition, the novel rubber belt has the characteristics of firmness, durability, good elasticity, difficult deformation, corrosion resistance, insulation, stiffness, easy washing, quick drying and the like, and is popular among people. The high-density polyester fabric is also popular with consumers as a case fabric, but the dye is not easy to permeate into the fiber in the dyeing process of the high-density polyester fabric, the coloring rate of the fiber is poor, the durable color fastness of the fabric can only reach 3-4 grades and cannot meet the use requirement, so the price of the fabric is influenced due to poor quality, and the added value of the product is low.
The dyeing percentage of a fiber is also called the dye uptake percentage, and specifically refers to the ratio of the amount of dye that is loaded onto the fiber during the dyeing process to the total amount of dye that is used. The dyeing rate of the fiber is not only related to the characteristics of the fiber, but also has great relation with the dye type, the pH value of the dye solution, the dyeing temperature, the heat preservation time and the dyeing rate in the dyeing process. The higher the coloring rate of the fiber, the more appropriate the dyeing condition is, the better the control of the cost is, and the fabric can be ensured in the aspect of color fastness. The high-density polyester fabric with higher color fastness is more widely applied in the field of bags and suitcases, and the added value and the economic benefit of the product are higher.
The Chinese patent with publication number CN111455700A discloses a method for dyeing and finishing a cationic polyester fabric, which comprises the following steps of: desizing; reducing the alkali; preparing a dye, namely compounding a disperse dye and a cationic dye; dyeing by a two-step method at high temperature and high pressure in one bath; soaping; reduction cleaning; and (6) shaping. The dyeing method has the defects that the problem that the high-density polyester fabric for the case fabric is difficult to dye is not solved, although two dyes are compounded and the dyeing process is improved, the color fastness of the dyed polyester fabric is only 3-4 grades.
Disclosure of Invention
In order to solve the problem that the high-density polyester fabric for the luggage fabric is difficult to dye, the invention provides a dyeing method of the polyester fabric for the luggage fabric with high color fastness, which improves the color fastness performance to reach the European standard (ISO105B02) level 5 by optimizing the existing dyeing process, improves the added value of the fabric and obtains better economic benefit.
The specific technical scheme of the invention is as follows: the invention provides a dyeing method of polyester fabric for high-color-fastness luggage fabric, which comprises the following steps: immersing the polyester fabric into a dye solution for dyeing, heating up from room temperature at a heating rate of 0.5-1 ℃/min, then carrying out heat preservation treatment at 130-140 ℃ for 20-30 min, and finally cooling to room temperature at a cooling rate of-6-1 ℃/min; the dye solution comprises disperse dye, acetic acid and a leveling agent.
The terylene belongs to polyester fibers, and because the terylene has a compact structure, high crystallinity and polymerization degree and strong hydrophobicity, and is difficult to obtain a good dyeing effect at normal temperature and normal pressure, in order to obtain good dyeing rate of the terylene luggage fabric, the invention enables the disperse dye to be effectively adsorbed into the amorphous region of the polyester fibers at a certain temperature by optimizing the dyeing process. When the polyester fiber is at about 130 ℃, the chain segment moves violently, the intermolecular gap is opened, and the dye can be quickly adsorbed into the amorphous area of the fiber. The solubility and the high-temperature dispersion stability of the disperse dye can be optimized by slowly heating (the heating rate is 0.5-1 ℃/min); after the temperature is raised to 130-140 ℃, the temperature is kept for a certain time, and the dye is absorbed into the amorphous area of the fiber; and then cooling to room temperature to shrink the amorphous area of the fiber, so that dye molecules are fixed in the fiber, and the fiber is dyed to obtain firm and deep color. The dye molecules can be ensured to have sufficient time to permeate into the interior of the polyester fiber and be firmly fixed in an amorphous area, and the microscopic combination can ensure that the polyester fabric has better stability when being subjected to the actions of washing, solarization, friction and the like, thereby ensuring that the polyester fabric has relatively higher dyeing fastness.
In addition, a pH buffer system is added into the disperse dye to adjust the pH value of the dye solution and improve the dyeing uniformity, and in addition, a proper amount of leveling agent is added into the dye bath to improve the solubility of the disperse dye and control the dye-uptake rate at the same time, so that the phenomenon of uneven dyeing is avoided. In order to improve the color fastness performance of the existing product to reach the 5-grade European standard (ISO105B02), improve the additional value of the fabric, and influence the color fastness by the dye type, dyeing temperature, heat preservation time, dyeing speed and the like in the dyeing method, the high-density polyester fabric has the optimal color fastness under the dyeing condition of the invention.
Preferably, the polyester fabric isThe gram weight is 200-400 g/m2。
Preferably, the pH value of the dye liquor is 4-6.
Experiments show that the dye with the pH value of 4-6 has excellent dispersion stability, excellent color and absorption of the disperse dye and optimal dyeing degree and fixation rate. Moreover, the weak acid environment is maintained in the system, so that the disperse dye is prevented from being hydrolyzed or chromophoric groups are prevented from being reduced.
Preferably, the bath ratio of the dye liquor is 1: 5 to 10.
Preferably, the temperature reduction is as follows: the temperature is reduced to 90-100 ℃ from 130-140 ℃ at a cooling rate of-3 to-1 ℃/min, and then the temperature is reduced to room temperature at a cooling rate of-6 to-4 ℃/min.
The temperature reduction process is performed at first at a slow speed and then at a fast speed, so that the shrinkage of the amorphous area of the polyester fiber can be regulated and controlled, and dye molecules can be better fixed in the fiber.
Preferably, the dyeing method further comprises a surface pretreatment step of the polyester fabric and a dyeing post-treatment step of the polyester fabric.
Preferably, the surface pretreatment step of the polyester fabric comprises the following steps: dispersing sesbania powder and trehalose in water, adding nano titanium dioxide particles, performing ultrasonic treatment, adding succinic anhydride and citric acid, stirring and reacting at 60-90 ℃ for 2-6 hours to obtain a modified nano titanium dioxide hydrosol; and (3) soaking the polyester fabric into the modified nano titanium dioxide hydrosol in a dark place, keeping the temperature at 30-40 ℃ for 20-40 min, and then taking out and drying.
The surface pretreatment of the polyester fabric before dyeing can improve the dye uptake of disperse dye, the modified nano titanium dioxide hydrosol can form a rough and uneven surface on the surface of the polyester fabric, the specific surface area of dyeing is increased, and the effect of deepening is achieved. The nano titanium dioxide also has good ultraviolet-proof functional characteristics and can improve the added value of polyester fabrics, but the compatibility between the nano titanium dioxide and the polyester fabrics is poor, and the prepared hydrosol utilizes the complexing adsorption effect and the crosslinking fixation effect of sesbania powder aqueous solution to improve the dispersibility and the compatibility. The addition of trehalose can promote disperse dyes to enter gaps among polyester molecules for dyeing, and the severe movement of molecular chains is helpful for the permeation of dye molecules because the glass transition temperature of trehalose is lower than that of polyester. In addition, the polyester fabric after surface treatment can adsorb disperse dyes more easily, and the hydrogen bond acting force between hydroxyl groups rich on the surface and polar groups (such as hydroxyl groups, amino groups and the like) in the molecules of the disperse dyes is also beneficial to improving the dye uptake.
Preferably, the particle size of the nano titanium dioxide particles is not more than 100 nm; the mass ratio of the sesbania powder to the trehalose to the water is 1-3: 0.5-1.5: 100 to 150 parts; the sesbania powder, the nano titanium dioxide particles, the succinic anhydride and the citric acid are mixed in a mass ratio of 10: 0.4-1: 1-3: 0.5 to 2.
The particle size of the nano titanium dioxide particles can influence the surface pretreatment effect of the polyester fabric, and the larger the particle size is, the more adverse the combination stability and the dye-uptake uniformity are, and the appearance quality of the polyester is influenced. In addition, the addition proportion among the raw materials influences the binding performance among substances, and also influences the effect of the disperse dye molecules entering the interior of the polyester molecules to realize effective dyeing, so that the dye-uptake and the color fastness are improved.
Preferably, the dyeing post-treatment step of the polyester fabric comprises the following steps: and (3) soaking the dyed polyester fabric into a mixed solution of trifluoroethylene acrylate, acrylamide, citric acid, magnesium acetate and water, heating to 70-80 ℃, preserving heat for 1-3 hours, and then taking out the polyester fabric and drying.
The dyeing post-treatment step can improve the color fastness of the polyester fabric, and the hyperbranched polymer is generated by in-situ crosslinking reaction on the surface of the fabric, so that the escape of dye molecules in the states of washing, solarization, friction, sweat stain and the like is reduced, and the dyeing fastness is improved. And, through selecting for use low refractive index fluorine-containing resin at polyester fiber surface film forming, reduce the refracting index, have obvious deepening effect to dyeing fabric look outward appearance, can also avoid disperse dyestuff sublime from polyester fabric in the heat setting to give polyester fabric surface hydrophobicity, further promote polyester fabric's dyeing fastness.
Preferably, the mass ratio of the trifluoroethylene acrylate to the acrylamide to the citric acid to the magnesium acetate to the water is 5-10: 1-4: 2-5: 0.1-1: 200-300.
Compared with the prior art, the invention has the following advantages:
